Question

each of the two smaller angels of a parallelogram measures 18 less than each of the two larger angles. find the measures of the four angles? @Jim_thompson5910

Answer 1

"each of the two smaller angles of a parallelogram measures 18 less than each of the two larger angles"

x = larger angle
x-18 = smaller angle

Answer 2

(x-18) + (x) = 180

solve for x

Answer 3

i got 162?

Answer 4

(x-18) + (x) = 180
x-18+x = 180
2x-18 = 180
2x-18+18 = 180+18 ... Add 18 to both sides.
2x+0 = 198
2x = 198
x = ????

Answer 5

99?

Answer 6

yes, so x-18 = 99-18 = 81
